Most fitness apps give you an algorithm and leave you to figure it out alone. We think that's backwards. 12REPS was built on a simple idea: everyone deserves a proper coach, not just those who can afford £80 an hour. Will Duru — a London-based personal trainer with over 10 years' experience — and Team Design's every programme in this app. He's the one who answers your messages. He's the one who reviews your form videos. He's the one who checks in when you go quiet. We're not trying to be the biggest fitness app. We're trying to be the one that actually works — because there's a real human behind it who gives a damn whether you show up or not. Strength training changed our lives. We built 12REPS to make sure it can change yours, too.
No gym? No problem. No experience? We've got you. 12REPS adapts to your reality. Tell us what equipment you have — a full gym, a pair of dumbbells, or just your bodyweight, and your programme is built around it. Tell us you're a complete beginner, and we start you with the fundamentals. Tell us you've been lifting for years, and we'll challenge you. You don't need to figure out what to do. You just need to show up. Will handles the rest.
Your goal. Your equipment. Your schedule. Your programme adapts as you get stronger, because Will and the Team are paying attention, not just an algorithm.
Every exercise comes with a video demo and coaching cues from Will — so you're never guessing whether you're doing it right. Every set, every rep, every weight gets logged. You'll see your numbers climbing week by week. That's not motivation. That's proof. And when you're unsure? Message Will. Send a form check video. Get a real answer from a real coach. You're not figuring this out alone.
The reason most people quit isn't laziness. It's isolation. When nobody notices if you skip a session, skipping becomes easy. That's why 12REPS puts you in a squad — a small group of others with the same goal. They see when you check in. You see when they do. No likes, no followers, no performance. Just a handful of people doing the work alongside you. Will drops into the chat. Members share wins and bad days. Someone notices when you go quiet. It's not social media. It's accountability.
Hi, I'm Will Duru, a personal trainer based in London and the founder of 12REPS. Over the past decade, I've had the privilege of watching hundreds of people discover strength they didn't know they had and smash goals they once thought were out of reach. These transformations—that's what drives me.
Step into the gym with confidence, follow expert-backed plans, and see consistent progress.
12REPS is a strength training app with a real personal trainer behind it. Will Duru — a London-based PT with over 10 years’ experience — designs the programmes, creates the exercise tutorials, and is available to answer your questions directly.
You get weekly workouts tailored to your goals and equipment, 1,500+ exercises with video demonstrations, and the ability to message Will when you need help. It’s the closest thing to having a PT in your pocket.
12REPS gives you a personal trainer experience through your phone. Here’s how it works:
1. Tell us about you
When you sign up, you answer a few questions: your goal (build muscle, lose fat, get stronger), your experience level, what equipment you have access to, and how many days a week you can train.
2. Get your programme
Based on your answers, you receive a structured training programme designed by Will Duru, a certified PT with over 10 years’ experience. This isn’t random exercise generation — it’s proper programming with progressive overload built in.
3. Train
Open the app, start your workout, and follow along. Each exercise has a video demonstration showing proper form. Log your sets, reps, and weights as you go — takes seconds.
4. Progress
The app tracks everything. You’ll see your lifts going up, your volume increasing, and your consistency building over time. Will adjusts your programme as you progress.
5. Get support
This is where 12REPS is different:
That’s it
Yes — you don’t need a gym to get strong.
When you set up your profile, you tell us exactly what equipment you have access to. If that’s nothing but your body and a bit of floor space, we’ll build your workouts around that.
No equipment? No problem:
Got minimal equipment?
Even a single pair of dumbbells or a resistance band opens up hundreds of additional exercises. Tell us what you’ve got and your programme adapts.
Equipment options we cater for:
The app doesn’t assume you have access to anything. You tell us your reality, and Will builds your programme around it.
No turning up to a workout and discovering you need a cable machine you don’t have.
12REPS focuses on strength training — the most effective way to build muscle, burn fat, and change how your body looks and performs.
You’ll find programmes for:
Every programme is designed by Will Duru, a certified PT with over 10 years’ experience, using proven training principles — progressive overload, proper volume, balanced muscle development.
Workout formats include:
Equipment options:
You tell us what you’ve got access to, and your workouts are built around it. No showing up to a session and finding out you need equipment you don’t have.
Yes — 12REPS is built for beginners just as much as experienced lifters.
When you set up your profile, you tell us your experience level. If you’re new to strength training, your programme starts with foundational movements, manageable volume, and clear progression. No throwing you into advanced techniques you’re not ready for.
What beginners get:
The truth is, beginners often get better results than experienced lifters — you’re starting fresh, building habits right, and your body responds quickly to new stimulus.
12REPS makes sure you do it properly from day one.
Premium includes weekly workouts from Will, direct messaging, form checks, squad access, and priority support.
Most fitness apps give you an algorithm. 12REPS gives you a coach.
Will builds programmes based on real training principles, not just randomised exercises. You can message him directly. You can send a video of your squat and get feedback on your form. And you can join a squad of others with the same goal — they’ll notice when you show up, and when you don’t.
The app has 1,500+ exercises with video demos, easy set-by-set tracking, and works whether you’re in a full gym or training at home with a pair of dumbbells.
Record a short video of yourself doing an exercise (15 seconds or less), submit it through the app, and Will sends you feedback — what you’re doing well, what to adjust, and how to improve.
It’s the thing people actually pay PTs for. Now it’s in your pocket.
Yes — Premium members can message Will and the team directly through the app. He typically replies within 24 hours. Ask about your programme, flag an injury, or just check you’re on the right track.
Download 12REPS free on the App Store or Google Play. Set up your profile, tell us your goal and equipment, and get your first workout in minutes.
If you want the full experience — Will in your corner, a team of personal trainers behind you — upgrade to Premium when you’re ready.
Yes. No contracts, no cancellation fees. You can cancel through the app or your app store subscription settings.
Over 1,500 strength exercises, each with:
Whether you’re learning a Romanian deadlift for the first time or looking for a new tricep finisher, it’s in there.
